Chelsea piled on the pressure - Costa plauged the Arsenal defence with high-energy runs, but each time he was thwarted by dogged defending.But the home side finally breached the def me on 52 minutes and it was simplify itself.A curling clipped free-kick by Fabregas was met by the glancing head of in-running Kurt Zouma who swept the ball past Cech from close range.Despite a strong showing with 10 minutes of the game left, the visitors went into self-destruct mode when already booked Santi Cazola needlessly scythed down Cesar Azpilicutea and was handed a second yellow card then a red.It was effectively game over but with the first minute of five added minutes at the end of the game, time the Blues doubled their lead through the boot of Hazard from just inside the Arsenal penalty area.It took a deflection on the way past Cech off Chambers, but Hazard will claim it, Chambers certainly won't
